Conversation
📝 WalkthroughWalkthroughThe service health check now uses a 45-second Windows budget and a 20-second budget on other platforms. It performs one 500 ms grace probe after the deadline and reports the measured wait duration on failure. ChangesService health confirmation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change extends Windows service readiness to 45 seconds and adds a final grace-period probe while preserving fail-closed exits. Merge readiness is currently reduced because the regression tests do not yet pin the required Windows budget or prove that zero-budget callers perform exactly one probe; this is a bounded test-assurance issue rather than evidence of a production logic failure.

On Windows, `ocx service repair` reported failure at its fixed 20s health deadline for a service that bound a few seconds later and then stayed healthy. The cold start does NTFS ACL hardening and previous-session journal recovery before the listener is announced, so 20s is not always enough, and the caller's fallback to a terminal failure is to start a second proxy against a port that is about to be taken. Windows now gets a 45s budget; the other platforms keep 20s. The wait also knocks once more after a short grace when the deadline passes, because the probe that ran last started before the deadline and a service binding during it was reported as dead. A caller that passed a zero budget still gets the single probe it asked for. The failure message prints the time actually waited. It printed the 20s constant whatever timeoutMs the caller passed. Refs lidge-jun#3009.

Restore the exact zero-budget assertion.
At Line 3148, toBeGreaterThanOrEqual(1) also passes if confirmServiceServing({ timeoutMs: 0 }) incorrectly performs a grace sleep and a second probe. The zero-budget contract requires only the immediate probe. Use toBe(1) here, and keep the greater-than-one assertion in the positive-timeout grace test.

Requesting changes on exact head b9c837c9c4d0f31c716ef2c5e37a522202c839a5.
The platform-specific budget and one final post-deadline probe are reasonable for #3009, but the current regression contract is weakened in two places already identified by the unresolved inline review:
- Restore
toBe(1)for the zero-budget case. WithtoBeGreaterThanOrEqual(1), a future implementation can incorrectly sleep and perform grace probes even when the caller explicitly requested no wait, and the test still passes. The positive-timeout test is the correct place to require multiple probes. - Pin the selected Windows budget exactly (
SERVICE_INSTALL_HEALTH_WINDOWS_MS/45_000), while continuing to assert Linux and macOS remain onSERVICE_INSTALL_HEALTH_MS. A merely-relative assertion does not protect the product decision this PR introduces.
This head is behind current dev and has only hygiene/target checks. Please resolve those focused test gaps, rebase, and run exact-head Windows/service CI before another review.

Superseded by #3104, which keeps your production logic exactly as written — the Windows budget, the Two test changes. The zero-budget assertion is restored to #3104 also carries the #3064 fix, because both are in Triaged in the 2026-08-31 non-priority-70 bug round. |

Both of your points about the tests are right, and they are the same mistake in two shapes. Closing in favour of #3104.
The Windows budget. I asserted The common fault is that in both places I wrote the assertion that my change happened to satisfy rather than the one the requirement states. That is the same habit that produced the hole you found in #3067: a fixture chosen to agree with the code instead of to probe it. The production logic you kept is unchanged, so there is nothing left here that #3104 does not carry. Thank you for the reimplementation and for saying which parts held up — that is more useful than a merge would have been. |
…er paths (rebase of #3104) (#3134) * fix(service): give a Windows cold start room to bind, without loosening zero budget Reimplements #3039 (author @ntdatt812), whose diagnosis and production logic are both right. confirmServiceServing had a fixed 20s deadline and returned as soon as the clock passed it. A Windows cold start does NTFS ACL hardening and previous- session journal recovery before the listener exists, so #3009 recorded a service that bound a few seconds late and then stayed healthy -- reported as a terminal failure with exit 1. The caller's fallback is to start a second proxy against a port that is about to be taken, which is worse than waiting. Windows now gets 45s, every other platform keeps 20s, and the loop knocks once more after a short grace before calling it dead. Two changes to #3039 as submitted: - It relaxed `expect(probes).toBe(1)` to `toBeGreaterThanOrEqual(1)` in the zero-budget test. That assertion is what stops a future change from sleeping when the caller asked not to wait, and "at least one" passes against exactly the version it is meant to forbid. The `waited` guard already preserves the contract, so the original assertion is restored and the comment says why. - Its Windows-budget test asserted only `toBeGreaterThan(linux)`, which accepts 21s. The reported service bound past 20s, so the number is the contract: the test now pins 45_000 absolutely. Mutation-checked, both restored afterwards: remove the `waited` guard -> 181 pass / 1 fail, the zero-budget test remove the grace probe -> 181 pass / 1 fail, the #3009 test Closes #3009. * fix(service): forgive only what the code page mangled in a scheduler path Reimplements #3067 (author @ntdatt812). The diagnosis is right and the relocation is right: schtasks converts its XML through the console code page before the bytes exist, so runFile reading as a buffer cannot help. A profile named outside that page comes back as C:\Users\???\... and the exact comparison rejected a registration this process had just created correctly, so `ocx service install` rolled it back (#3064). The remedy needed narrowing. #3067 compiles every unrepresentable run to `[^\\/]*`, which forbids a path separator but allows arbitrary ASCII. A segment that is ENTIRELY non-ASCII then has no anchors left, so C:\Users\<CJK>\.opencodex\service-launcher.vbs matches C:\Users\Admin\.opencodex\service-launcher.vbs and this process would adopt, repair, or delete another account's task. The same hole applies to <UserId>, where MACHINE\<CJK> would match MACHINE\Admin. Its tests use "Người", whose surviving Ng and i letters hide the case. Here an unrepresentable run may match only a run of substitution characters -- '?' per character, U+FFFD, or nothing -- and every ASCII segment, including every separator, is matched literally. A foreign account's path fails because "admin" is not a run of substitutions. Mutation-checked: widening the class back to `[^\\/]*` gives 186 pass / 1 fail, exactly "rejects another account's path that is merely the same shape". Closes #3064. * fix(service): bind scheduler recovery to exact SID * fix(service): fail closed on ambiguous scheduler ownership * test(service): lock scheduler ownership guards * test(service): scope scheduler verification fixtures * test(service): exercise scheduler ownership oracles

This PR is deliberately staying open. #3134 landed on What landed. The Windows cold-start budget (45s, pinned absolutely rather than as an inequality) and the final probe at the deadline. Your diagnosis drove both. What did not. The diagnostic message. This PR prints the time actually waited: // src/service.ts:742-753 (this PR)
const startedAt = elapsed();
...
+ `${Math.max(1, Math.round((elapsed() - startedAt) / 1000))}s.\n`with the comment stating exactly why: "The elapsed time, not the constant: a caller that passes its own timeoutMs used to be told it had waited 20s whatever it waited." What landed prints the configured budget instead: // src/service.ts:742-750 (on dev now)
const healthBudgetMs = deps.timeoutMs ?? serviceInstallHealthMs();
...
+ `${Math.trunc(healthBudgetMs / 1000)}s.\n`Why that matters more now than before. #3134 also adds a post-deadline grace knock, so the real wait can exceed the budget. The printed number can therefore understate the time actually spent — which is the defect this PR set out to fix, reintroduced by the change that supersedes it.

The diagnostic half that #3134 deliberately left open is now #3138 — the failure line reports the wait actually spent, grace knock included, instead of the configured budget. That closes out everything this PR was carrying: the production logic went in through #3134, and the two test criticisms above were fair and are not being re-litigated. |

That prime calls getValidCodexToken, which can rotate the very credential these assertions read, and fetches a real host unless the stub is up. Both fixtures installed Date.now and globalThis.fetch AFTER startServer, leaving a window two dynamic import() resolutions wide where the prime ran against the real clock and real fetch. On a warm local module cache it resolved before the fixture finished; on a loaded CI runner it did not, and seenAuth[0] was already the rotated token. Measured rather than assumed: OPENCODEX_DEBUG_QUOTA=1 prints refreshed=1 on every run of both the fixed and unfixed trees, so the prime always fires. The fix does not suppress it -- it makes it run inside the fixture's controlled world. The thread-affinity test at :2131 had the identical shape and is fixed too.

Fixes #3009.
ocx service repairreported a terminal failure at its 20s health deadline for a service that bound a few seconds later and then stayed healthy. This follows the review on the issue, which asked for a longer Windows budget, a final probe at the deadline, and a message that prints the real wait.What changed
Windows gets a 45s budget; nothing else changes. The cold start does NTFS ACL hardening and previous-session journal recovery before the listener is announced, so the 20s that is plenty elsewhere is not always enough there.
serviceInstallHealthMs(platform)keeps the other platforms onSERVICE_INSTALL_HEALTH_MS, so a healthy Linux or macOS install cannot be slowed down by this.One more knock after the deadline. The loop's last probe starts before the deadline, so a service that binds while that probe is in flight was reported as dead. It now waits a short grace and knocks once more before calling it a failure.
A caller that passed a zero budget still gets exactly the single probe it asked for —
waitedis only set once a sleep has actually happened, so "do not wait" keeps meaning that.The message prints the time actually waited. It printed
SERVICE_INSTALL_HEALTH_MSwhatevertimeoutMsthe caller passed, so a caller with its own budget was told it had waited 20 seconds regardless.process.exitCode = 1on a genuine failure is unchanged. As the comment there says, the GUI update worker reads the child's exit status, and a registered-but-silent service must not look like a successful update.Tests

The grace probe adds one when the caller did give the wait some time, so the exact count is no longer the contract — it is nowtoBeGreaterThanOrEqual(1), which is what the test's own name asks and still catches a version that returns without knocking at all. Flagging it explicitly since changing an existing assertion deserves a look.Not in this PR
#3008 came out of the same recovery session but is a different file and a different failure point, and the review asked to keep them apart. Same for the ACL hardening itself (#3011), which is assigned.
